What is the expected life of a battery backup?
I may be in the wrong forum, but just yell at me and I will go away.
Two or three years ago, at least, I purchased two APC battery backups for three computers, printer, monitor, etc. The units have functioned flawlessly during the years; whenever there is a power outage, 3 or 4 times a year, I have time to wrap up and shut down, without a problem. I have no idea where the manuals are and not sure if I would believe the manufacturer, anyway.
What is the expected life of these units? Should I expect 3-5 years, or 5-10 years, or what? Just curious.
